特開２００８−２３６９２１号公報JP 2008-236921 A

近年、ステータやロータが大型化している。そして、これに伴いこれらを構成するコアのサイズが大型化している。そして、コアのティース部に巻回される巻線は径の大きいものが使用される。このような大型のコアは、磁性板材等を積層して構成するコアを用いた場合、積層枚数が増大し、コア高さが高くなる。
このような、コア高さが高い大型のコアのティース部に巻線を巻回する場合、巻線張力によりコアのティース部のみが集中的に締め付けられて積層方向に歪む。そして、コアのヨーク部背面が、コアの高さ方向に弓なり変形するという問題がある。また、巻線の径が大きくなるため、巻線張力が増大する。よって、この巻線張力の増大によりヨーク部背面の弓なり変形がより顕著になるという問題がある。
上記特許文献１に示すような従来の治具は、巻線の巻回時の分割コアの位置ズレを有る程度抑制するが、上記のような近年の大型のコアを想定したものではなく、コアのヨーク部背面の弓なり変形を抑制することはできない。In recent years, stators and rotors have become larger. Along with this, the size of the cores constituting these has increased. And the thing with a large diameter is used for the coil | winding wound by the teeth part of a core. When such a large core is formed by stacking magnetic plate materials or the like, the number of stacked layers increases and the core height increases.
When the winding is wound around the teeth portion of the large core having a high core height, only the teeth portion of the core is intensively tightened due to the winding tension and is distorted in the stacking direction. And there exists a problem that the yoke part back surface of a core deform | transforms into a bow in the height direction of a core. Further, the winding tension increases because the winding diameter increases. Therefore, there is a problem that the bow deformation on the back of the yoke portion becomes more remarkable due to the increase in winding tension.
The conventional jig as shown in the above-mentioned Patent Document 1 suppresses the positional deviation of the split core at the time of winding of the winding, but it does not assume the recent large core, but the core The bow-shaped deformation of the back of the yoke cannot be suppressed.

この発明は、上記のような課題を解決するためになされたもので、磁性板材を積層して構成するコアのティース部に巻線を巻回した際に生じるヨーク部背面の弓なり変形を抑制することのできる巻線装置、巻線方法、およびこの巻線方法を用いた電機子の製造方法を得ることを目的とする。   The present invention has been made to solve the above-described problems, and suppresses the bow-like deformation of the back of the yoke portion that occurs when the winding is wound around the teeth portion of the core formed by stacking magnetic plate materials. An object of the present invention is to obtain a winding device, a winding method, and an armature manufacturing method using the winding method.

The overlapping portion of the core piece 2 is provided with a convex portion 31a and a concave portion 31b. And it is stopped by inserting the convex part 31a into the concave part 31b. And the connection part 31 which connects the adjacent core piece 2 so that bending is possible is comprised by the convex part 31a and the recessed part 31b. The connecting portion 31 may have any configuration as long as the adjacent core pieces 2 are connected so as to be bendable, and is not limited to the example of the first embodiment.

次に、図１を参照し、このようなコア部材１のコア片２のティース部４に巻線２０を巻回する巻線装置１００について説明する。なお、以下の説明において、コア片２は、ヨーク部３のティース部４が突出する側の面としてのティース突出面と、ティース突出面と反対側の面としてのヨーク部３背面とを有するものとする。   Next, with reference to FIG. 1, the winding apparatus 100 which winds the coil | winding 20 around the teeth part 4 of the core piece 2 of such a core member 1 is demonstrated.

まず、コア保持部５の構成について説明する。
コア保持部５は、コア片２の積層方向の一方向としての上側に配置される、第１部材としての上側ピンホルダ５ａと、積層方向の他方向としての下側に配置される、第２部材としての下側ピンホルダ５ｂとを有している。
各ピンホルダ５ａ、５ｂは各回転軸５１ａ、５１ｂにそれぞれ固定されている。そして、回転軸５１ａ、５１ｂは、略回転体形状で、本実施の形態１では円盤状の回転体にて構成されている。各回転軸５１ａ、５１ｂは、回転軸固定部５２ａ、５２ｂにより回転中心が規制されている。そして、回転動力５３ａ、５３ｂを駆動することにより、各ピンホルダ５ａ、５ｂは回転軸５１ａ、５１ｂを中心に間欠回転駆動される（図中矢印Ｃ参照）。なお、両回転軸５１ａ、５１ｂの軸中心は一致している。First, the configuration of the core holding unit 5 will be described.

Each pin holder 5a, 5b is being fixed to each rotating shaft 51a, 51b, respectively. The rotating shafts 51a and 51b have a substantially rotating body shape, and are configured by a disk-shaped rotating body in the first embodiment. The rotation centers of the rotation shafts 51a and 51b are regulated by the rotation shaft fixing portions 52a and 52b. Then, by driving the rotational power 53a, 53b, the pin holders 5a, 5b are intermittently driven around the rotation shafts 51a, 51b (see arrow C in the figure). In addition, the shaft centers of both rotating shafts 51a and 51b are coincident.

Then, the pin holders 5a and 5b are intermittently linearly driven in the stacking direction of the core pieces 2 by the linear motion parts 58a and 58b (see arrow D in the figure). In addition, in order to make the structure of the core holding part 5 easy to understand, the description of the rotating shaft fixing part 52a and the rotating power 53a is omitted on the plan view of FIG.

上側ピンホルダ５ａは、コア片２が配置される側の端面に、ヨーク部３に設けられた開口部３０と嵌合する、第１の凸部としての略円筒形状の保持ピン５４ａが設けられている。保持ピン５４ａは、巻線２０を巻回するコア片２（以下、図１の説明においてコア片２１と記す）の保持に用いられる。
また、上側ピンホルダ５ａには、巻線２０を巻回するコア片２に隣接するコア片２の内、一方側のコア片２（以下、図１の説明においてコア片２２と記す）の姿勢を保持する姿勢保持部が設けられている。本実施の形態１における姿勢保持部は、保持ピン５４ａから一方側に所定角度θ回転した位置に設けられた、第３の凸部としての姿勢保持ピン５６ａである。そして、姿勢保持ピン５６ａの形状は、保持ピン５４ａと同形状にて形成されている。姿勢保持ピン５６ａは一方側のコア片２２のヨーク部３に設けられた開口部３０と嵌合することにより、コア片２２の姿勢を保持する。The upper pin holder 5a is provided with a substantially cylindrical holding pin 54a as a first convex portion that fits with the opening 30 provided in the yoke portion 3 on the end surface on the side where the core piece 2 is disposed. Yes. The holding pin 54a is used to hold the core piece 2 (hereinafter referred to as the core piece 21 in the description of FIG. 1) around which the winding 20 is wound.
Further, the upper pin holder 5a has the posture of one of the core pieces 2 adjacent to the core piece 2 around which the winding 20 is wound (hereinafter referred to as the core piece 22 in the description of FIG. 1). An attitude holding unit for holding is provided. The posture holding portion in the first embodiment is a posture holding pin 56a as a third convex portion provided at a position rotated by a predetermined angle θ from the holding pin 54a to one side. The shape of the posture holding pin 56a is the same as that of the holding pin 54a. The posture holding pin 56a is held in the posture of the core piece 22 by fitting with the opening 30 provided in the yoke portion 3 of the core piece 22 on one side.

また、保持ピン５４ａから１８０度回転した位置には、後述するチャック機構６のスライド部材６０と係合する、第２の凸部としての係合ピン５５ａが設けられている。
また、上側ピンホルダ５ａには、バネ５７ａが内在している。そして、バネ５７ａは保持ピン５４ａが設けられる位置と回転軸５１ａとの間に配置されている。Further, at a position rotated 180 degrees from the holding pin 54a, an engagement pin 55a serving as a second convex portion that engages with a slide member 60 of the chuck mechanism 6 described later is provided.
The upper pin holder 5a has a spring 57a. The spring 57a is disposed between the position where the holding pin 54a is provided and the rotation shaft 51a.

下側ピンホルダ５ｂの構成は、上側ピンホルダ５ａの構成とほぼ同様であり、両ピンホルダ５ａ、５ｂは互いに対向するように配置されている。
下側ピンホルダ５ｂには、保持ピン５４ｂと、姿勢保持ピン５６ｂと、係合ピン５５ｂとが設けられている。上側ピンホルダ５ａと同様、保持ピン５４ｂは巻線２０を巻回するコア片２１の保持に用いられる。係合ピン５５ｂは後述するチャック機構６のスライド部材６０と係合する。姿勢保持ピン５６ｂの形成位置は、上側ピンホルダ５ａの姿勢保持ピン５６ａと異なっており、保持ピン５４ｂから他方側に所定角度θ回転した位置に配置される。下側ピンホルダ５ｂの姿勢保持ピン５６ｂは、巻線２０を巻回するコア片２１に隣接するコア片２の内、他方側のコア片２（以下、図１の説明においてコア片２３と記す）の姿勢を保持するために用いられる。
また、下側ピンホルダ５ｂの保持ピン５４ｂが設けられる位置と、回転軸５１ｂとの間には、上側ピンホルダ５ａの場合と同様、バネ５７ｂが内在されている。The configuration of the lower pin holder 5b is substantially the same as the configuration of the upper pin holder 5a, and the both pin holders 5a and 5b are arranged to face each other.
The lower pin holder 5b is provided with a holding pin 54b, a posture holding pin 56b, and an engagement pin 55b. Similar to the upper pin holder 5a, the holding pin 54b is used to hold the core piece 21 around which the winding 20 is wound. The engagement pin 55b engages with a slide member 60 of the chuck mechanism 6 described later. The position of the posture holding pin 56b is different from the posture holding pin 56a of the upper pin holder 5a, and is arranged at a position rotated by a predetermined angle θ from the holding pin 54b to the other side. The posture holding pin 56b of the lower pin holder 5b is the core piece 2 on the other side of the core pieces 2 adjacent to the core piece 21 around which the winding 20 is wound (hereinafter referred to as the core piece 23 in the description of FIG. 1). It is used to maintain the posture.
A spring 57b is provided between the position where the holding pin 54b of the lower pin holder 5b is provided and the rotation shaft 51b, as in the case of the upper pin holder 5a.

コア保持部５を構成する上側ピンホルダ５ａ、下側ピンホルダ５ｂにより、巻線２０を巻回するコア片２１およびその両隣に配置されるコア片２２、２３の連続する３個のコア片２１、２２、２３が、各ティース部４が互いに離間する方向となるように各ピンホルダ５ａ、５ｂの外周面に沿って保持される。この時、巻線２０を巻回するコア片２１に隣接するコア片２２、２３の各ティース部４が、コア片２１のティース突出面よりヨーク部３側となるように、隣接するコア片２２、２３の姿勢が保持されるよう、上側ピンホルダ５ａの姿勢保持ピン５６ａ、下側ピンホルダ５ｂの姿勢保持ピン５６ｂの配設位置が決定されている。   By the upper pin holder 5a and the lower pin holder 5b constituting the core holding portion 5, the core piece 21 around which the winding 20 is wound and the three core pieces 21, 22 which are continuous to each other are disposed. , 23 are held along the outer peripheral surfaces of the pin holders 5a and 5b so that the teeth portions 4 are in a direction away from each other. At this time, the adjacent core pieces 22 are arranged such that the tooth portions 4 of the core pieces 22 and 23 adjacent to the core piece 21 around which the winding 20 is wound are closer to the yoke portion 3 side than the teeth projecting surface of the core piece 21. The positions of the posture holding pins 56a of the upper pin holder 5a and the posture holding pins 56b of the lower pin holder 5b are determined so that the postures 23 and 23 are held.

次に、チャック機構６の構成について説明する。
チャック機構６は、巻線２０を巻回するコア片２１のヨーク部３背面と対向する係止面６１ａを備えたチャック本体６１と、チャック本体６１を固定基準としてスライドするスライド部材６０と、スライド部材６０を駆動する直動動力６２とにより構成されている。スライド部材６０のスライドする方向は巻線２０を巻回するコア片２１のティース部４の突出方向と反対方向（図１中、矢印Ｅの方向）である。Next, the configuration of the chuck mechanism 6 will be described.
The chuck mechanism 6 includes a chuck body 61 having a locking surface 61a facing the back surface of the yoke portion 3 of the core piece 21 around which the winding 20 is wound, a slide member 60 that slides with the chuck body 61 as a fixed reference, and a slide It is comprised by the linear motion power 62 which drives the member 60. FIG. The sliding direction of the slide member 60 is the direction opposite to the protruding direction of the teeth portion 4 of the core piece 21 that winds the winding 20 (the direction of arrow E in FIG. 1).

スライド部材６０は、コア保持部５の上側ピンホルダ５ａと係合する第１スライド部６０ａと、コア保持部５の下側ピンホルダ５ｂと係合する第２スライド部６０ｂとからなる。第１スライド部６０ａは上側ピンホルダ５ａの係合ピン５５ａと係合する穴部６５ａを備え、第２スライド部６０ｂは下側ピンホルダ５ｂの係合ピン５５ｂと係合する穴部６５ｂを備えている。   The slide member 60 includes a first slide part 60 a that engages with the upper pin holder 5 a of the core holding part 5 and a second slide part 60 b that engages with the lower pin holder 5 b of the core holding part 5. The first slide portion 60a includes a hole portion 65a that engages with the engagement pin 55a of the upper pin holder 5a, and the second slide portion 60b includes a hole portion 65b that engages with the engagement pin 55b of the lower pin holder 5b. .

第１、第２スライド部６０ａ、６０ｂの穴部６５ａ、６５ｂにそれぞれ係合ピン５５ａ、５５ｂが挿入されることで、コア保持部５とスライド部材６０とが係合する。そして、スライド部材６０をスライドさせると、コア保持部５が巻線２０を巻回するコア片２１のティース部４の突出方向と反対方向に引っ張られる。そして、コア保持部５が引っ張られることにより、コア保持部５に保持された巻線２０を巻回するコア片２１のヨーク部３背面が、係止面６１ａに押圧されることとなる（後に説明する図８参照）。   The core holding portion 5 and the slide member 60 are engaged with each other by inserting the engagement pins 55a and 55b into the holes 65a and 65b of the first and second slide portions 60a and 60b, respectively. When the slide member 60 is slid, the core holding part 5 is pulled in the direction opposite to the protruding direction of the teeth part 4 of the core piece 21 around which the winding 20 is wound. And when the core holding part 5 is pulled, the yoke part 3 back surface of the core piece 21 which winds the coil | winding 20 hold | maintained at the core holding part 5 will be pressed by the locking surface 61a (afterwards). (See FIG. 8 for explanation).

なお、係止面６１ａは、巻線２０を巻回するコア片２１のヨーク部３の背面全体を係止できるよう、少なくともヨーク部３背面と同等の大きさを有している。また、係止面６１ａは、ヨーク部３背面の形状に合わせた形状としておくことが望ましい。本実施の形態１におけるコア片２のヨーク部３背面は図２に示すように平面視緩やかな弧状の曲面である。よって、係止面６１ａの形状は、ヨーク部３背面の形状に合わせ、ヨーク部３背面に平行な曲面にて形成している。また、例えば、ヨーク部３背面の形状が、曲面ではなく平面で形成されている場合が考えられる。その場合、係止面６１ａの形状はヨーク部３背面の形状に合わせ、ヨーク部３背面に平行な平面にて形成すればよい。   Note that the locking surface 61 a has at least the same size as the back surface of the yoke portion 3 so that the entire back surface of the yoke portion 3 of the core piece 21 around which the winding 20 is wound can be locked. Further, it is desirable that the locking surface 61a has a shape that matches the shape of the back surface of the yoke portion 3. The back surface of the yoke portion 3 of the core piece 2 in the first embodiment is an arcuate curved surface that is gentle in plan view as shown in FIG. Therefore, the shape of the locking surface 61 a is formed by a curved surface parallel to the back surface of the yoke portion 3 in accordance with the shape of the back surface of the yoke portion 3. For example, the case where the shape of the back surface of the yoke part 3 is not a curved surface but a flat surface can be considered. In that case, the shape of the locking surface 61a may be formed in a plane parallel to the back surface of the yoke portion 3 in accordance with the shape of the back surface of the yoke portion 3.

上記のようなチャック機構６は、直動部品６３を介して固定基準となる設備６４に取り付けられている。そして、直動部品６３は、チャック機構６全体を、巻線２０を巻回するコア片２１と近づいたり遠ざけたりするよう直線駆動される（図中矢印Ｆ参照）。なお、設備６４には、規制部材６４ａが設けられている。そして、規制部材６４ａと直動部品６３とが接することで、コア片２１方向に移動するチャック機構６の移動範囲が規制される。   The chuck mechanism 6 as described above is attached to a facility 64 serving as a fixed reference via a linear motion component 63. The linear motion component 63 is linearly driven so as to move the chuck mechanism 6 as a whole toward or away from the core piece 21 around which the winding 20 is wound (see arrow F in the figure). The facility 64 is provided with a regulating member 64a. Then, the movement range of the chuck mechanism 6 that moves in the direction of the core piece 21 is regulated by contacting the regulating member 64 a and the linear motion component 63.

Further, in the cross-sectional views (B) of each drawing, the description of the core pieces other than the core piece at the winding position of the winding 20 is omitted so that the configuration of the core holding part 5 can be easily understood.

（工程Ｓ１）コア部材搬送工程（図４および図１３（Ｃ−４）参照）
コア部材搬送工程では、コア部材１が直線状に配置された状態で、巻線装置１００内に投入される。コア保持部５の各ピン（保持ピン５４ａ，５４ｂ、姿勢保持ピン５６ａ，５６ｂ、係合ピン５５ａ，５５ｂ）の位置関係は図１３（Ｃ−４）に示す通りであり、上側ピンホルダ５ａの保持ピン５４ａと、下側ピンホルダ５ｂの姿勢保持ピン５６ｂとが対向するような位置関係となっている。(Process S1) Core member conveyance process (refer to Drawing 4 and Drawing 13 (C-4))
In the core member conveying step, the core member 1 is put into the winding device 100 in a state where the core member 1 is linearly arranged. The positional relationship of each pin (holding pins 54a and 54b, posture holding pins 56a and 56b, engaging pins 55a and 55b) of the core holding unit 5 is as shown in FIG. 13C-4, and the holding of the upper pin holder 5a. The positional relationship is such that the pin 54a and the posture holding pin 56b of the lower pin holder 5b face each other.

図４（Ａ）、図４（Ｂ）に示すように、巻線装置１００内に投入されたコア部材１は、投入方向端部に位置する１個目のコア片２（以下、図４〜図１１に基づく巻線方法の説明においてコア片２ａと記す）のヨーク部３に設けられた開口部３０の位置が、上側ピンホルダ５ａの保持ピン５４ａの直下となる位置まで移動する。そして、コア保持部５の上側ピンホルダ５ａ、下側ピンホルダ５ｂがそれぞれコア片２ａに近づく方向に直線駆動される。そして、コア片２ａのヨーク部３両端面の各開口部３０に、上側ピンホルダ５ａの保持ピン５４ａおよび下側ピンホルダ５ｂの姿勢保持ピン５６ｂがそれぞれ挿入される。   As shown in FIG. 4A and FIG. 4B, the core member 1 thrown into the winding device 100 is a first core piece 2 (hereinafter referred to as FIG. The position of the opening 30 provided in the yoke portion 3 of the core piece 2a in the description of the winding method based on FIG. 11 moves to a position immediately below the holding pin 54a of the upper pin holder 5a. Then, the upper pin holder 5a and the lower pin holder 5b of the core holding part 5 are linearly driven in a direction approaching the core piece 2a. Then, the holding pins 54a of the upper pin holder 5a and the posture holding pins 56b of the lower pin holder 5b are inserted into the openings 30 on both end surfaces of the yoke portion 3 of the core piece 2a.

（工程Ｓ２）姿勢変形工程（図５および図１３（Ｃ−５）参照）
姿勢変形工程では、上側ピンホルダ５ａと下側ピンホルダ５ｂとが同時に反時計回りに所定角度θ回転する。よって、このことで直線状に配置されたコア部材１の姿勢が変形し、１個目のコア片２ａが図５（Ａ）に示すように、巻線２０の巻回位置に移動する。なお、１個目のコア片２ａが巻線巻回位置に移動することにより、コア片２ａに隣接する２個目のコア片２（以下、図４〜図１１に基づく巻線方法の説明においてコア片２ｂと記す）がコア片２ａが移動する前の位置に移動する。(Step S2) Posture Deformation Step (See FIGS. 5 and 13 (C-5))
In the posture deformation process, the upper pin holder 5a and the lower pin holder 5b simultaneously rotate counterclockwise by a predetermined angle θ. Therefore, the posture of the core member 1 arranged in a straight line is deformed by this, and the first core piece 2a moves to the winding position of the winding 20 as shown in FIG. When the first core piece 2a is moved to the winding position, the second core piece 2 adjacent to the core piece 2a (hereinafter, in the description of the winding method based on FIGS. 4 to 11). The core piece 2b) is moved to a position before the core piece 2a is moved.

（工程Ｓ３）コア保持部の退避および回転工程（図６および図１３（Ｃ−６）参照）
姿勢変形工程後、コア保持部５の上側ピンホルダ５ａ、下側ピンホルダ５ｂはそれぞれコア片２ａから遠ざかる方向に一旦退避する。よって、上側ピンホルダ５ａの保持ピン５４ａ、および、下側ピンホルダ５ｂの姿勢保持ピン５６ｂはコア片２ａの開口部３０から抜かれる。そして、下側ピンホルダ５ｂのみが時計回りに所定角度θ回転し、姿勢変形前の位置に復帰する。この時のコア保持部５の各ピンの位置関係は図６（Ｂ）、図１３（Ｃ−６）に示すように、上側ピンホルダ５ａの保持ピン５４ａと下側ピンホルダ５ｂの保持ピン５４ｂとが対向し、上側ピンホルダ５ａの係合ピン５５ａと下側ピンホルダ５ｂの係合ピン５５ｂとが対向するような位置関係となる。(Step S3) Retraction and rotation step of the core holding part (see FIG. 6 and FIG. 13 (C-6))
After the posture deformation process, the upper pin holder 5a and the lower pin holder 5b of the core holding part 5 are temporarily retracted in the direction away from the core piece 2a. Therefore, the holding pin 54a of the upper pin holder 5a and the posture holding pin 56b of the lower pin holder 5b are removed from the opening 30 of the core piece 2a. Then, only the lower pin holder 5b rotates clockwise by a predetermined angle θ and returns to the position before the posture deformation. At this time, as shown in FIGS. 6B and 13C-6, the positional relationship of the pins of the core holding portion 5 is such that the holding pin 54a of the upper pin holder 5a and the holding pin 54b of the lower pin holder 5b. The positional relationship is such that the engaging pin 55a of the upper pin holder 5a faces the engaging pin 55b of the lower pin holder 5b.

（工程Ｓ４）チャック機構前進工程（図７および図１３（Ｃ−７）参照）
次に、図７に示すように、チャック機構６全体が直動部品６３により直線駆動され、１個目のコア片２ａ方向に前進する。チャック機構６は、チャック本体６１の係止面６１ａが、巻線２０が巻回される１個目のコア片２ａのヨーク部３背面と密着する位置まで前進する。この時、第１スライド部６０ａの穴部６５ａは上側ピンホルダ５ａの係合ピン５５ａと対向し、第２スライド部６０ｂの穴部６５ｂは下側ピンホルダ５ｂの係合ピン５５ｂと対向している。(Step S4) Chuck mechanism advancement step (see FIG. 7 and FIG. 13 (C-7))
Next, as shown in FIG. 7, the entire chuck mechanism 6 is linearly driven by the linear motion component 63 and moves forward in the direction of the first core piece 2a. The chuck mechanism 6 advances to a position where the locking surface 61a of the chuck body 61 comes into close contact with the back surface of the yoke portion 3 of the first core piece 2a around which the winding 20 is wound. At this time, the hole 65a of the first slide portion 60a faces the engagement pin 55a of the upper pin holder 5a, and the hole 65b of the second slide portion 60b faces the engagement pin 55b of the lower pin holder 5b.

（工程Ｓ５）コア片保持工程（図８および図１４（Ｃ−８）参照）
次に、図８に示すように、コア保持部５が再びコア片２ａに近づく方向に直線駆動される。そして、コア片２ａのヨーク部３両端面の各開口部３０に、上側ピンホルダ５ａの保持ピン５４ａおよび下側ピンホルダ５ｂの保持ピン５４ｂがそれぞれ挿入され、コア片２ａが保持される。
同時に、上側ピンホルダ５ａの係合ピン５５ａおよび下側ピンホルダ５ｂの係合ピン５５ｂが、第１スライド部６０ａの穴部６５ａおよび第２スライド部６０ｂの穴部６５ｂにそれぞれ挿入される。そして、上側ピンホルダ５ａと第１スライド部６０ａとが係合し、下側ピンホルダ５ｂと第２スライド部６０ｂとが係合する。(Step S5) Core piece holding step (see FIG. 8 and FIG. 14 (C-8))
Next, as shown in FIG. 8, the core holding part 5 is linearly driven in a direction approaching the core piece 2a again. Then, the holding pin 54a of the upper pin holder 5a and the holding pin 54b of the lower pin holder 5b are respectively inserted into the openings 30 on both end surfaces of the yoke part 3 of the core piece 2a, and the core piece 2a is held.
At the same time, the engaging pin 55a of the upper pin holder 5a and the engaging pin 55b of the lower pin holder 5b are inserted into the hole 65a of the first slide portion 60a and the hole 65b of the second slide portion 60b, respectively. Then, the upper pin holder 5a and the first slide portion 60a are engaged, and the lower pin holder 5b and the second slide portion 60b are engaged.

また、この時、１個目のコア片２ａに隣接する２個目のコア片２ｂにおける積層方向の下側の開口部３０には、下側ピンホルダ５ｂの姿勢保持ピン５６ｂが挿入され、コア片２ｂの姿勢が保持される。２個目のコア片２ｂの保持位置は、コア片２ｂのティース部４が、１個目のコア片２ａのティース突出面よりヨーク部３側となる位置である。   At this time, the posture holding pin 56b of the lower pin holder 5b is inserted into the lower opening 30 in the stacking direction of the second core piece 2b adjacent to the first core piece 2a. 2b is maintained. The holding position of the second core piece 2b is a position where the tooth portion 4 of the core piece 2b is closer to the yoke portion 3 side than the tooth protruding surface of the first core piece 2a.

なお、本実施の形態１では係合ピン５５ａ、５５ｂの大きさに対し、穴部６５ａ、６５ｂの大きさを少し大きめに設定している。よって、穴部６５ａ、６５ｂの大きさには余裕があり、係合ピン５５ａ、５５ｂの挿入を行いやすく構成している。なお、穴部６５ａ、６５ｂの形状は、係合ピン５５ａ、５５ｂとの係合によりコア保持部５を引っ張ることができればどのような形状でもよい。本実施の形態１では、例として断面四角形状の穴部６５ａ、６５ｂを設けたが、これに限られるものではない。   In the first embodiment, the sizes of the holes 65a and 65b are set slightly larger than the sizes of the engagement pins 55a and 55b. Therefore, the holes 65a and 65b have a sufficient size, and the engagement pins 55a and 55b can be easily inserted. The hole portions 65a and 65b may have any shape as long as the core holding portion 5 can be pulled by engagement with the engagement pins 55a and 55b. In the first embodiment, the holes 65a and 65b having a square cross section are provided as an example, but the present invention is not limited to this.

（工程Ｓ６）コア片固定および巻線工程（図９および図１４（Ｃ−９）参照）
次に、図９に示すように、チャック本体６１の位置を固定したまま、スライド部材６０の第１スライド部６０ａ、第２スライド部６０ｂを直動動力６２によりスライドさせる。従って、コア保持部５の上側ピンホルダ５ａ、下側ピンホルダ５ｂが巻線２０が巻回される１個目のコア片２ａのティース部４の突出方向と反対方向に引っ張られる。これにより、上側ピンホルダ５ａ、下側ピンホルダ５ｂに保持されたコア片２ａのヨーク部３の背面全体が、チャック本体６１の係止面６１ａに押圧され、巻線２０が巻回される１個目のコア片２ａが確実に固定される。(Step S6) Core piece fixing and winding step (see FIG. 9 and FIG. 14 (C-9))
Next, as shown in FIG. 9, the first slide portion 60 a and the second slide portion 60 b of the slide member 60 are slid by the linear motion power 62 while the position of the chuck body 61 is fixed. Accordingly, the upper pin holder 5a and the lower pin holder 5b of the core holding portion 5 are pulled in the direction opposite to the protruding direction of the teeth portion 4 of the first core piece 2a around which the winding 20 is wound. As a result, the entire back surface of the yoke portion 3 of the core piece 2a held by the upper pin holder 5a and the lower pin holder 5b is pressed against the locking surface 61a of the chuck body 61, and the winding 20 is wound first. The core piece 2a is securely fixed.

この時、上側ピンホルダ５ａ、下側ピンホルダ５ｂにはバネ５７ａ、５７ｂが内在されているため、上側ピンホルダ５ａ、下側ピンホルダ５ｂを引っ張ることによる張力がコア保持部５の回転軸５１ａ、５１ｂに直接掛かることを防止することができる。
その後、巻線供給巻付用のフライヤ７を巻線開始位置に移動させ、コア片２ａのヨーク部３の背面全体をチャック本体６１の係止面６１ａに押圧する。そして、このコア片２ａを係止した状態で、コア片２ａのティース部４にフライヤ７により巻線２０を巻回する。なお、フライヤ７は、図示しない巻線ヘッドに装着され、ティース部４の周りを旋回しつつ巻線２０を供給し、ティース部４に巻線２０を巻回する。At this time, since the upper pin holder 5a and the lower pin holder 5b include springs 57a and 57b, the tension generated by pulling the upper pin holder 5a and the lower pin holder 5b is directly applied to the rotation shafts 51a and 51b of the core holding part 5. It is possible to prevent hanging.
Thereafter, the flyer 7 for winding supply winding is moved to the winding start position, and the entire back surface of the yoke portion 3 of the core piece 2 a is pressed against the locking surface 61 a of the chuck body 61. And the winding 20 is wound by the fryer 7 around the teeth part 4 of the core piece 2a in the state which latched this core piece 2a. Note that the flyer 7 is attached to a winding head (not shown), supplies the winding 20 while turning around the tooth portion 4, and winds the winding 20 around the tooth portion 4.

（工程Ｓ７）巻線完了工程
図１０および図１４（Ｃ−１０）は、上記各工程により１個目のコア片２ａのティース部４への巻線が終わり、フライヤ７を退避させた状態を示す。巻線終了後、コア保持部５の上側ピンホルダ５ａ、下側ピンホルダ５ｂがそれぞれコア片２ａから遠ざかる方向に直線駆動する。よって、コア片２ａのヨーク部３両端面の各開口部３０から、上側ピンホルダ５ａの保持ピン５４ａおよび下側ピンホルダ５ｂの保持ピン５４ｂが抜かれる。また、２個目のコア片２ｂの開口部３０から、下側ピンホルダ５ｂの姿勢保持ピン５６ｂが抜かれる。その後、チャック機構６全体をコア片２ａから遠ざかる方向に退避させる。(Step S7) Winding Completion Step FIG. 10 and FIG. 14 (C-10) show the state in which the winding to the tooth portion 4 of the first core piece 2a is completed and the flyer 7 is retracted by the above steps. Show. After the end of the winding, the upper pin holder 5a and the lower pin holder 5b of the core holding part 5 are linearly driven in a direction away from the core piece 2a. Therefore, the holding pin 54a of the upper pin holder 5a and the holding pin 54b of the lower pin holder 5b are pulled out from the openings 30 on both end surfaces of the yoke part 3 of the core piece 2a. Further, the posture maintaining pin 56b of the lower pin holder 5b is pulled out from the opening 30 of the second core piece 2b. Thereafter, the entire chuck mechanism 6 is retracted in a direction away from the core piece 2a.

（工程Ｓ８）上記工程Ｓ２〜Ｓ７の繰り返し
コア保持部５、チャック機構６の退避後、２個目のコア片２ｂへの巻線２０の巻回に移る。まず、上記工程Ｓ２の姿勢変形工程により、２個目のコア片２ｂを巻線２０の巻回位置に移動させ、続いて工程Ｓ３〜Ｓ７を行い、２個目のコア片２ｂへの巻線２０の巻回を行う。なお、図１１および図１４（Ｃ−１１）に、２個目のコア片２ｂにおけるコア片固定および巻線工程を示す。
３個目以降のコア片も同様に巻線２０を巻回する。コア部材１を構成するコア片２の個数分（ここでは９個分）工程Ｓ２〜Ｓ７を繰り返すことで、全てのコア片２に巻線２０が巻回される。(Step S8) Repeat Steps S2 to S7 After the core holding part 5 and the chuck mechanism 6 are retracted, the winding 20 is wound around the second core piece 2b. First, the second core piece 2b is moved to the winding position of the winding 20 by the posture changing step of the above step S2, and then steps S3 to S7 are carried out to wind the second core piece 2b. 20 turns. FIG. 11 and FIG. 14 (C-11) show the core piece fixing and winding steps in the second core piece 2b.
The windings 20 are similarly wound on the third and subsequent core pieces. By repeating steps S2 to S7 for the number of core pieces 2 constituting the core member 1 (here, 9 pieces), the windings 20 are wound around all the core pieces 2.

（工程Ｓ９）最後のコア片の姿勢変形後、コア部材を搬出する工程
最後のコア片２ｉへの巻線完了後、コア片２ｉの姿勢変形を行い、コア部材１が直線状に配置された状態にし、コア部材１を巻線装置１００から搬出する。これによりコア部材１への巻線工程が終了する。(Step S9) Step of unloading the core member after the last core piece is deformed After the winding to the last core piece 2i is completed, the posture of the core piece 2i is changed and the core member 1 is arranged in a straight line. The core member 1 is unloaded from the winding device 100. Thereby, the winding process to the core member 1 is completed.

全ての巻線工程が終了後、コア部材１の各連結部３１を屈曲させて各コア片２のティース部４が内側となるように環状に配置する。そして、コア部材１の両端部のコア片２のヨーク部３同士を溶接等で固着することにより、図３に示すような固定子１０が完成する。   After all the winding steps are completed, the respective connecting portions 31 of the core member 1 are bent so that the teeth portions 4 of the respective core pieces 2 are arranged in an annular shape. And the stator 10 as shown in FIG. 3 is completed by adhering the yoke parts 3 of the core pieces 2 at both ends of the core member 1 by welding or the like.

以上のような巻線方法および巻線装置１００により、本実施の形態１では下記の効果が得られる。
まず、巻線装置１００のコア保持部５は上側ピンホルダ５ａ、下側ピンホルダ５ｂとから構成されている。そして、上側ピンホルダ５ａ、下側ピンホルダ５ｂの保持ピン５４ａ、５４ｂと、巻線２０を巻回するコア片２の積層方向両端面の各開口部３０とが嵌合することにより、コア片２を保持している。そして、上側ピンホルダ５ａ、下側ピンホルダ５ｂは、スライド部材６０の第１スライド部６０ａ、第２スライド部６０ｂとそれぞれ係合する。巻線２０の巻回時には、スライド部材６０がスライドすることで、上側ピンホルダ５ａ、下側ピンホルダ５ｂが同時に引っ張られ、コア片２のヨーク部３背面がチャック本体６１の係止面６１ａに押圧される。With the winding method and the winding apparatus 100 as described above, the following effects can be obtained in the first embodiment.
First, the core holding part 5 of the winding device 100 includes an upper pin holder 5a and a lower pin holder 5b. Then, the holding pins 54a and 54b of the upper pin holder 5a and the lower pin holder 5b and the openings 30 on both end surfaces in the stacking direction of the core piece 2 around which the winding 20 is wound are fitted to each other. keeping. The upper pin holder 5a and the lower pin holder 5b engage with the first slide portion 60a and the second slide portion 60b of the slide member 60, respectively. When the winding 20 is wound, the slide member 60 slides, whereby the upper pin holder 5 a and the lower pin holder 5 b are pulled simultaneously, and the back surface of the yoke portion 3 of the core piece 2 is pressed against the locking surface 61 a of the chuck body 61. The

コア片２は、上側ピンホルダ５ａ、下側ピンホルダ５ｂにより積層方向両端側で保持される。さらに、上側ピンホルダ５ａ、下側ピンホルダ５ｂが第１スライド部６０ａ、第２スライド部６０ｂにより同時に引っ張られるため、その引っ張り力はコア片２の積層方向両端側へ作用し、コア片２のヨーク部３背面を係止面６１ａへ押圧する力となる。   The core piece 2 is held at both ends in the stacking direction by the upper pin holder 5a and the lower pin holder 5b. Further, since the upper pin holder 5a and the lower pin holder 5b are simultaneously pulled by the first slide portion 60a and the second slide portion 60b, the pulling force acts on both ends of the core piece 2 in the stacking direction, and the yoke portion of the core piece 2 3 It becomes the force which presses the back surface to the locking surface 61a.

一般に、このように磁性板材が積層され形成されたコア片のティース部に巻線を巻回する際、巻線張力によりティース部のみが集中的に締め付けられる。特に、積層枚数が多い大型コア片に巻線を巻回する場合には、巻線張力による締め付けによりティース部が積層方向に圧縮され、ヨーク部背面が積層方向弓なりに変形するような力が働く。   Generally, when a winding is wound around a tooth portion of a core piece formed by stacking magnetic plate materials in this way, only the teeth portion is intensively tightened by winding tension. In particular, when winding a winding around a large core piece with a large number of layers, the teeth are compressed in the stacking direction by tightening with the winding tension, and a force is exerted so that the back of the yoke is deformed into a bow in the stacking direction. .

しかし、本発明の巻線方法および巻線装置１００では、コア片２のうち変形力が大きいヨーク部３の積層方向両端側を作用点として、コア片２のヨーク部３背面全体が係止面６１ａに押圧された状態で、コア片２のティース部４への巻線の巻回を行うことができる。このため、巻線２０の巻回によりコア片２のティース部４のみが集中的に締め付けられたとしても、コア片２のヨーク部３背面は係止面６１ａに沿って伸ばされた状態で巻線２０が巻回され、コア片２のヨーク部３背面における積層方向の弓なり変形を抑制することができる。   However, in the winding method and the winding device 100 of the present invention, the entire back surface of the yoke portion 3 of the core piece 2 is the locking surface with the both ends in the stacking direction of the yoke portion 3 having a large deformation force in the core piece 2 as the working point. The winding of the winding around the tooth portion 4 of the core piece 2 can be performed while being pressed by 61a. For this reason, even if only the teeth portion 4 of the core piece 2 is intensively tightened by the winding 20, the back of the yoke portion 3 of the core piece 2 is wound in a state of being stretched along the locking surface 61 a. The wire 20 is wound, and the bow deformation in the stacking direction on the back surface of the yoke portion 3 of the core piece 2 can be suppressed.

そして、コア片２の弓なり変形を抑制することができるため、ティース部４の積層方向両端面を平行に保った状態で巻線２０を巻回することができ、巻線２０の整列性の向上を図ることができる。
さらに、コア片２の弓なり変形を抑制することができることにより、コア片２の形状精度が向上し、複数のコア片２を環状配置して形成される固定子１０の真円度を向上させ、耐久性の高い高精度な固定子１０を得ることができる。And since the bow-shaped deformation | transformation of the core piece 2 can be suppressed, the winding 20 can be wound in the state which kept the both ends of the lamination direction of the teeth part 4 in parallel, and the alignment of the winding 20 is improved. Can be achieved.
Furthermore, by suppressing the bow deformation of the core piece 2, the shape accuracy of the core piece 2 is improved, and the roundness of the stator 10 formed by annularly arranging a plurality of core pieces 2 is improved, The highly accurate stator 10 having high durability can be obtained.

また、巻線２０を巻回するコア片２は、ヨーク部３背面が係止面６１ａに押圧されて係止される。そして、この係止面６１ａを備えたチャック本体６１は、固定基準となる設備６４に取り付けられている。このため、係止面６１ａの位置が押圧力により変位することがない。従って、コア片２の巻線の巻回位置は一定となる。よって、コア片２とフライヤ７との相対位置が明確となるため、巻線２０の整列性をさらに向上させることができる。   Moreover, the core piece 2 which winds the coil | winding 20 is latched by the yoke part 3 back surface being pressed by the latching surface 61a. The chuck body 61 provided with the locking surface 61a is attached to a facility 64 serving as a fixing reference. For this reason, the position of the locking surface 61a is not displaced by the pressing force. Therefore, the winding position of the winding of the core piece 2 is constant. Therefore, since the relative position between the core piece 2 and the flyer 7 becomes clear, the alignment of the windings 20 can be further improved.

また、本実施の形態１のように、コア保持部５の略円筒状の保持ピン５４ａ、５４ｂをコア片２のヨーク部３に設けられた断面略円形の開口部３０に挿入することにより、コア片２を保持する構成は、構造的な剛性が高い。従って、コア保持部５がスライド部材６０により引っ張られた際に保持ピン５４ａ、５４ｂによりコア片２の開口部３０に掛かる力によって、開口部３０が変形したり、破損することを防止することができる。   Further, as in the first embodiment, by inserting the substantially cylindrical holding pins 54a and 54b of the core holding portion 5 into the opening 30 having a substantially circular cross section provided in the yoke portion 3 of the core piece 2, The structure that holds the core piece 2 has high structural rigidity. Therefore, it is possible to prevent the opening 30 from being deformed or damaged by the force applied to the opening 30 of the core piece 2 by the holding pins 54a and 54b when the core holding part 5 is pulled by the slide member 60. it can.

また、コア保持部５の上側ピンホルダ５ａ、下側ピンホルダ５ｂに設けられた姿勢保持ピン５６ａ、５６ｂを、巻線２０を巻回するコア片２に隣接するコア片２のヨーク部３の開口部３０に挿入する。このことで、隣接する各コア片のティース部４が、巻線２０を巻回するコア片２のヨーク部３におけるティース突出面よりヨーク部３側に配置されるように各コア片を保持する。従って、コア片２にフライヤ７で巻線２０を巻回する際に、隣接する各コア片２とフライヤ７とが干渉することがなく、巻線２０の巻回を精度よく行うことができる。   In addition, the posture holding pins 56 a and 56 b provided on the upper pin holder 5 a and the lower pin holder 5 b of the core holding part 5 are connected to the opening of the yoke part 3 of the core piece 2 adjacent to the core piece 2 around which the winding 20 is wound. 30. By this, each core piece is hold | maintained so that the teeth part 4 of each adjacent core piece may be arrange | positioned from the teeth protrusion surface in the yoke part 3 of the core piece 2 which winds the coil | winding 20 at the yoke part 3 side. . Therefore, when the winding 20 is wound around the core piece 2 by the flyer 7, the adjacent core pieces 2 and the flyer 7 do not interfere with each other, and the winding 20 can be wound with high accuracy.

また、コア保持部５を構成する上側ピンホルダ５ａ、下側ピンホルダ５ｂは、回転体形状である円盤状である。この円盤状の各ピンホルダ５ａ、５ｂに設けられた保持ピン５４ａ、５４ｂ、姿勢保持ピン５６ａ、５６ｂにより、各ピンホルダ５ａ、５ｂの外周面に沿って、巻線２０を巻回するコア片２およびその両隣に位置する各コア片２の少なくとも連続する３個のコア片２のティース部４が互いに離間する方向となるように、３個のコア片２を保持することができる。このため、連続する３個のコア片２の保持を容易な構成により確実に行え、巻線の巻回精度向上を図ることができる。   Further, the upper pin holder 5a and the lower pin holder 5b constituting the core holding part 5 have a disk shape which is a rotating body shape. The core piece 2 for winding the winding 20 along the outer peripheral surface of each pin holder 5a, 5b by the holding pins 54a, 54b and the posture holding pins 56a, 56b provided on the disk-shaped pin holders 5a, 5b, and The three core pieces 2 can be held so that the teeth portions 4 of at least three consecutive core pieces 2 of the respective core pieces 2 located on both sides thereof are in a direction away from each other. For this reason, it is possible to reliably hold the three consecutive core pieces 2 with an easy configuration, and to improve the winding accuracy of the winding.

そして、上側ピンホルダ５ａ、下側ピンホルダ５ｂは、巻線２０を巻回するコア片２に隣接するコア片２のティース部４が、巻線２０を巻回するコア片２のティース突出面よりヨーク部３側となるように、隣接するコア片２を保持する。このため、巻線２０を巻回するコア片２への巻線の巻回を、隣接するコア片２と干渉することなくフライヤ７により行うことができる。   The upper pin holder 5a and the lower pin holder 5b are arranged so that the teeth 4 of the core piece 2 adjacent to the core piece 2 around which the winding 20 is wound are yoked from the teeth projecting surface of the core piece 2 around which the winding 20 is wound. The adjacent core piece 2 is hold | maintained so that it may become the part 3 side. For this reason, winding of the winding to the core piece 2 which winds the winding 20 can be performed by the flyer 7 without interfering with the adjacent core piece 2.

なお、本実施の形態１では、コア保持部５の上側ピンホルダ５ａおよび下側ピンホルダ５ｂと、スライド部材６０の第１スライド部６０ａおよび第２スライド部６０ｂとの係合は、上側ピンホルダ５ａ、下側ピンホルダ５ｂの係合ピン５５ａ、５５ｂを、第１スライド部６０ａの穴部６５ａ、第２スライド部６０ｂの穴部６５ｂにそれぞれ挿入することで行っていたが、必ずしもこれに限られるものではない。   In the first embodiment, the upper pin holder 5a and the lower pin holder 5b of the core holding part 5 and the first slide part 60a and the second slide part 60b of the slide member 60 are engaged with the upper pin holder 5a and the lower pin holder 5b. The engaging pins 55a and 55b of the side pin holder 5b are inserted into the hole 65a of the first slide part 60a and the hole 65b of the second slide part 60b, respectively, but this is not necessarily limited thereto. .

図１５を参照し、コア保持部５の上側ピンホルダ５ａおよび下側ピンホルダ５ｂと、スライド部材６０の第１スライド部６０ａおよび第２スライド部６０ｂとの係合構造の別例について説明する。なお、図１５（Ａ）、（Ｂ）は別例１、図１５（Ｃ）、（Ｄ）は別例２であり、図１５（Ａ）、図１５（Ｃ）は、上側ピンホルダ５ａの平面図、図１５（Ｂ）、図１５（Ｄ）は、図１５（Ａ）、図１５（Ｃ）の平面図におけるＡ−Ａ断面図を示す。なお、下側ピンホルダ５ｂと第２スライド部６０ｂとの係合構造は、上側ピンホルダ５ａと第１スライド部６０ａとの係合構造と同様であるため図および説明を省略する。 With reference to FIG. 15, another example of the engagement structure between the upper pin holder 5a and the lower pin holder 5b of the core holding part 5 and the first slide part 60a and the second slide part 60b of the slide member 60 will be described. 15A and 15B show another example 1, and FIGS. 15C and 15D show another example 2. FIGS. 15A and 15C show the plane of the upper pin holder 5a. FIGS. 15B and 15D are cross-sectional views taken along line AA in the plan views of FIGS. 15A and 15C. Note that the engagement structure between the lower pin holder 5b and the second slide portion 60b is the same as the engagement structure between the upper pin holder 5a and the first slide portion 60a, and thus illustrations and descriptions thereof are omitted.

例えば図１５（Ａ）、（Ｂ）の別例１は、上側ピンホルダ５ａに穴部５５０を設け、第１スライド部６０ａ側に係合ピン６５０を設けている。第１スライド部６０ａの係合ピン６５０を第１部材の穴部５５０に挿入することで、上側ピンホルダ５ａと第１スライド部６０ａとを係合させている。   For example, in another example 1 in FIGS. 15A and 15B, a hole 550 is provided in the upper pin holder 5a, and an engagement pin 650 is provided on the first slide portion 60a side. By inserting the engaging pin 650 of the first slide part 60a into the hole 550 of the first member, the upper pin holder 5a and the first slide part 60a are engaged.

また、例えば図１５（Ｃ）、（Ｄ）の別例２は、上側ピンホルダ５ａに断面略長方形状の係合ピン５５１を設け、第１スライド部６０ａに係合ピン５５１と係合する段差部６５１を設けている。上側ピンホルダ５ａの係合ピン５５１を第１スライド部６０ａの段差部６５１に引っかけることで、上側ピンホルダ５ａと第１スライド部６０ａとを係合させている。   Further, for example, in another example 2 of FIGS. 15C and 15D, the upper pin holder 5 a is provided with an engagement pin 551 having a substantially rectangular cross section, and the first slide portion 60 a is engaged with the engagement pin 551. 651 is provided. The upper pin holder 5a and the first slide portion 60a are engaged with each other by hooking the engaging pin 551 of the upper pin holder 5a to the step portion 651 of the first slide portion 60a.

このように、コア保持部５の上側ピンホルダ５ａおよび下側ピンホルダ５ｂと、スライド部材６０の第１スライド部６０ａおよび第２スライド部６０ｂとの係合構造は様々なバリエーションがあり、スライド部材６０によりコア保持部５を引っ張ることができればどのような構造であってもよい。   As described above, there are various variations in the engagement structure between the upper pin holder 5 a and the lower pin holder 5 b of the core holding portion 5 and the first slide portion 60 a and the second slide portion 60 b of the slide member 60. Any structure may be used as long as the core holding part 5 can be pulled.

また、本実施の形態１では、係止面６１ａはコア片２のヨーク部３背面と平行な曲面としたが、必ずしもこれに限られるものではない。
コア片の積層高さや、巻線の線径によって、巻線時のティース部への締め付け力は変わる。締め付け力が大きい場合には、巻線の巻回後にコア片の押圧固定を解除することで、締め付け力による戻りが生じ、コア片のヨーク部背面が弓なりに変形する場合がある。このような場合、例えば、係止面を、ヨーク部背面に対して積層方向上下側に反るような曲面としておくことで、コア片のヨーク部背面が係止面の曲面に沿って反った状態で巻線を巻回することができる。予めヨーク部背面が反った状態で巻線を巻回しておき、巻回時の反り量と巻回後の戻り量とが相殺されるように係止面の反り曲面を設定しておくことで、コア片のヨーク部背面の弓なり変形を抑制することができる。In the first embodiment, the locking surface 61a is a curved surface parallel to the back surface of the yoke portion 3 of the core piece 2, but is not necessarily limited to this.
Depending on the stacking height of the core pieces and the wire diameter of the winding, the tightening force on the tooth portion during winding varies. When the tightening force is large, there is a case where the back of the yoke portion of the core piece is deformed in a bow shape by releasing the pressing and fixing of the core piece after winding of the winding. In such a case, for example, by setting the locking surface to a curved surface that warps up and down in the stacking direction with respect to the back surface of the yoke portion, the yoke portion back surface of the core piece warps along the curved surface of the locking surface. The winding can be wound in the state. By winding the winding in a state where the back of the yoke part is warped in advance, the warping curved surface of the locking surface is set so that the warping amount at the time of winding and the return amount after winding are offset. Further, it is possible to suppress the bow-like deformation on the back surface of the yoke portion of the core piece.

また、本実施の形態１では、連結部を介して連結された複数のコア片のティース部に巻線を巻回する場合について説明した。他の例としては、各コア片が連結していない分割コア片のティース部に巻線を巻回する場合にも同様の考え方を適用できる。すなわち、分割コアのヨーク部背面を係止面に押圧した状態で巻線を巻回することで、分割コア片のヨーク部背面の弓なり変形を抑制することができる。   Moreover, in this Embodiment 1, the case where a coil | winding was wound around the teeth part of the several core piece connected via the connection part was demonstrated. As another example, the same idea can be applied to the case where the winding is wound around the teeth portion of the divided core pieces to which the core pieces are not connected. That is, by winding the winding in a state where the yoke part back surface of the split core is pressed against the locking surface, it is possible to suppress the bow deformation of the back surface of the yoke part of the split core piece.

また、本実施の形態１では、上側ピンホルダ５ａに隣接するコア片２のうち一方側のコア片２を保持する姿勢保持ピン５６ａを設け、下側ピンホルダ５ｂに隣接するコア片２のうち他方側のコア片２を保持する姿勢保持ピン５６ｂを設けた。しかし、姿勢保持ピンの配置等はこれに限られるものではない。他の例としては、上側ピンホルダ５ａに他方側のコア片２を保持する姿勢保持ピンを設け、下側ピンホルダ５ｂに一方側のコア片２を保持する姿勢保持ピンを設ける構成。また、他の例としては、上側ピンホルダ５ａ、下側ピンホルダ５ｂに姿勢保持ピンを２本ずつ設け、隣接する各コア片２を両側から姿勢保持ピンで保持する構成としてもよい。   Moreover, in this Embodiment 1, the attitude | position holding | maintenance pin 56a which hold | maintains one core piece 2 among the core pieces 2 adjacent to the upper side pin holder 5a is provided, and the other side among the core pieces 2 adjacent to the lower side pin holder 5b is provided. A posture holding pin 56b for holding the core piece 2 was provided. However, the arrangement and the like of the posture holding pins are not limited to this. As another example, a configuration in which a posture holding pin that holds the core piece 2 on the other side is provided in the upper pin holder 5a and a posture holding pin that holds the core piece 2 on the one side is provided in the lower pin holder 5b. As another example, two posture holding pins may be provided in the upper pin holder 5a and the lower pin holder 5b, and the adjacent core pieces 2 may be held by the posture holding pins from both sides.

また、本実施の形態１では、電機子の例として回転電機の固定子を採用し、固定子を構成するコア片への巻線方法について説明したが、電機子が固定子の場合に限られるものではなく、回転電機の回転子として機能する電機子や、リニアモータの電機子等にも適用することができ、積層型のコア片のヨーク部背面の弓なり変形を抑制することができる。   In the first embodiment, a stator of a rotating electric machine is employed as an example of the armature, and the winding method to the core piece constituting the stator has been described. However, the present invention is limited to the case where the armature is a stator. However, the present invention can be applied to an armature that functions as a rotor of a rotating electric machine, an armature of a linear motor, or the like, and can suppress bow deformation on the back of the yoke portion of the laminated core piece.

また、この発明は、その発明の範囲内において、実施の形態を適宜、変形、省略することが可能である。   Further, in the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.
